>>2722754I'm guessing you've probably read Sasaki To Miyano (pic related) already, as well as the classics like Zankoku na Kami ga Shihai Suru and what has been done of Kaze to Ki no Uta so far. I'm trying to remember some really old shit here...
>Haru wo Daite Ita Long as fuck, 14 volumes. It's kind of the archetype that all "actors get together" BL is based on.
>YatteranneezeLike 7 volumes long, I never read the whole thing but it was very popular back in the day.
>Kusatta Kyoushi no Houteishiki 10 volumes, I remember enjoying this a lot.
>Koori no Mamono no Monogatari24 fucking volumes, I know I read most of them ages ago too. It's fantasy.
>Tantei Aoneko6 vols, I think. This was one of my favourites a long time ago, but not for good reasons. The translation is hilariously bad, and the story goes bonkers after a while, but the art is very pretty. Can't really describe it as slow burn romance though.
>Marginal 5 volumes, but it's not really slow burn romance either... It feels more like classic fantasy/Sci Fi. It's good though, and the Haruomi Hosono soundtrack is great.
>Genwaku no Kodou Well over 100 chapters, gritty supernatural fantasy more than romance though.
>Animal XThis manga is complete insanity, unlike the rest of the mangaka's work. It had mpreg and weird were-dinosaurs and all kinds of crazy bullshit. I hated it at the time and still do, though it seems less weird now in the age of kemono and omegaverse. It's not my thing, but it is pretty long.
